“Like the great manager he is, he has told us what we need to do now, which is just to stay calm.

“He’s right because everything depends on us now. We know that the Premier League is complicated.

"It’s not easy so we know we have to improve. We all need to dig in and give something extra because we have this title in our hands and we can’t let it slip away.”
